i take my laptop to school (college, not high school. if you have one in high school, you are considered a tosser with rich parents who don't realise you don't need one in high school).
since the wifi network is pretty miss-or-miss (see what i did there?) i watch metalocalypse. and because people next to me have no respect for screen privacy, i will go to world.guns.ru or watch Xavier: Renegade Angel. and if i'm typing something i will switch to the biggest font i have and type "THIS IS NOT YOUR SCREEN" because i KNOW they are looking at it.
i do these things to make people uneasy around me, and think twice b4 looking at my screen.
like one time where i was on world.guns.ru:
Adam- "Oh, are you on the rifle team?"
Brandon-"No."
Adam-" You're not gonna... Columbine us-- are you?"
Brandon-" No."
Adam- "Well in case, just remember I'm your best friend, right?"
OH! also this one time i was reading Mein Kampf from a .pdf and this girl comes over and starts reading if off of my screen. she then says "oh, that's that book Hitler wrote, right? are you reading that for a class?"
i looked at her with a plain smile and said , "nope, i just like this book".
she backed away slowly.
